Damn it! forgot to turn on the mic in the best session.
I attached the Audio-Technica ATR-3350 in rear bumper for today's session, and in the 4th session, i forgot to turn on the mic. I looked at the videos of couple other sessions, they had amazing sound. i might get another one for the iphone to use it with HTL. currently mine is hooked up to gopro2

Here is a video taken with the Audio-Technica ATR-3350 Lavalier Omnidirectional Condenser Microphone (~$25). It comes with a 20 foot long cable that I routed from my front grille all the way to my trunk. I'm using a GoPro Hero2 attached to a bracket on my front license plate holder.

For normal street driving, I simply leave the microphone in the trunk and the connector hidden inside the front grille. When I'm at the track, I mount the GoPro on the front bracket, hook-up the connector and run the cable out of the trunk and tape the mic inside the rear bumber via the tow hook hole. I lost the foam that came with it so the video is using the mic with nothing to reduce wind noise. It probably would be even better if I put something on the mic for the wind noise.

For ~$25 and some labor to route and hide the cable, I'm pretty happy with the results...

Finally, to overlay my GoPro video and data from Trackmaster, I'm using Dashware. More info here:http://www.dashware.net/

This is a fairly inexpensive setup and works well for the occasional trip to the track. My only complain so far is that the G force data is sometime not that reliable. Not a big issue and this could be a problem with my phone and not the app itself.

I ran the mic wire from inside the trunk all the way to the front grill going inside the car. If I remember correctly, I had to remove the back seats (pretty easy to do) and the sill trim at both rear and front door (also pretty easy). The only difficult part is to go through the firewall between the front footwell area and the engine bay. I followed the instructions provided by EAS to get the wire from the passenger footwell over to the DME box. Here is the link to the instructions:http://www.m3post.com/forums/showthread.php?t=329420

Once the wire is in the engine bay, you can simply run it on the edge using zip ties all the way to the front grill. The mic wire was not quite long enough to make the whole run so I bought an 8' feet extension and made the connection inside the DME box.

I store the mic in the trunk for normal DD driving. When I go the the track, I run the mic wire out of the trunk and tape it inside the tow hook hole using regular painter's tape.

What mount/case do you use for the GoPro when using the external mic? I am assuming the skeleton mount is the one to buy so you can plug in the mic adapter? I dont really want to use the camera with the frame mount outside the car. GoPro really gets you with all of these different mounts and accessories

You can buy the skeleton housing, or use a tool like dremmel to cut out an opening on the side of the housing.

Yea, if you mount the cam outside the car, the housing, the lens cover, etc, really takes beating. On the GoPro (original model, not Hero 2 or 3) I've been using on the front bumper, I've changed the lens cover 3 times so far.

for gopro, I used a camera mount that attaches to the headrest. it places the gopro right between the two seats and gives great angle. you have to use the skeleton housing to attach the mic. I taped the mic on the rear bumper between the exhausts.i used painters tape to avoid damaging paint.

Color me stupid, but how are you recording the audio from the ATR-3350? I double checked, my HERO3 does not have a 3.5mm pickup/"headphone jack". Are you all using an independent audio recorder, and syncing the audio up with the go-pro video after the fact? Or is there a 3.5mm receiver-adaptor that can plug into the Go-Pro's mini HDMI port?

its a mini usb to 3.5mm jack adapter.....accessories make money so lets force them to buy more accessories! be careful with the mini usb port though and do not unplug anything at any sort of angle...mine broke already and had to be warrantied.
